Backup and restore

:::warning Local backups are only supported for docker-compose installs. If you want to backup a Kubernetes instance locally, use an S3-compatible server such as minio :::

Backup

:::note Local backups are enabled by default, and will be run daily at 00:00 :::

Local backups can be created by running the following command in your authentik installation directory

docker-compose run --rm worker backup
# Or for kubernetes
kubectl exec -it deployment/authentik-worker -c authentik -- ak backup

This will dump the current database into the ./backups folder. By defaults, the last 10 Backups are kept.

Restore

:::warning Currently, it is only supported to restore backups into the same version they have been taken from. Different versions might work, but this is not guarantee. Instead, install the version the backup was taken with, restore the backup and then upgrade. :::

Run this command in your authentik installation directory

The filename can be found by either looking into the ./backups directory or using S3.

docker-compose run --rm worker restore -i default-2020-10-03-115557.psql
# Or for kubernetes
kubectl exec -it deployment/authentik-worker -c authentik -- ak restore -i default-2020-10-03-115557.psql

After you've restored the backup, it is recommended to restart all services with docker-compose restart or kubectl restart deployment --all.

S3 Configuration

Preparation

authentik expects the bucket you select to already exist. The IAM User given to authentik should have the following permissions

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObjectAcl",
                "s3:GetObject",
                "s3:ListBucket",
                "s3:DeleteObject",
                "s3:PutObjectAcl"
            ],
            "Principal": {
                "AWS": "arn:aws:iam::example-AWS-account-ID:user/example-user-name"
            },
            "Resource": [
                "arn:aws:s3:::example-bucket-name/*",
                "arn:aws:s3:::example-bucket-name"
            ]
        }
    ]
}

docker-compose

Set the following values in your .env file.

AUTHENTIK_POSTGRESQL__S3_BACKUP__ACCESS_KEY=
AUTHENTIK_POSTGRESQL__S3_BACKUP__SECRET_KEY=
AUTHENTIK_POSTGRESQL__S3_BACKUP__BUCKET=
AUTHENTIK_POSTGRESQL__S3_BACKUP__REGION=

If you want to backup to an S3-compatible server, like minio, use this setting:

AUTHENTIK_POSTGRESQL__S3_BACKUP__HOST=http://play.min.io

Kubernetes

Simply enable these options in your values.yaml file

# Enable Database Backups to S3
authentik:
  postgresql:
    s3_backup:
      bucket: "authentik-backup"
      access_key: foo
      secret_key: bar
      region: eu-central-1
      # Optional S3 host
      # host: "https://backup-s3.beryju.org"

Afterwards, run a helm upgrade to update the ConfigMap. Backups are done automatically as above, at 00:00 every day.
